Arrangement for an attachment for an electrical device

ABSTRACT

Arrangement for an attachment for an electrical device, such as a reflector fitted with a bulb, which exhibits in the form of a pin or similar an electrical connection capable of being pushed into an electrical junction. The invention permits, among other things, the simple and effective attachment of an electrical device to an electrical cable. A coupling capable of being joined to an electrical cable, which coupling exhibits appropriate electrical connection devices which fit the electrical connection in question, is so arranged as to function as a stop both for an electrical device and for a holder capable of being joined to the electrical device.

The present invention relates to an arrangement for an attachment for anelectrical device, such as a reflector fitted with a bulb, whichexhibits in the form of a pin or similar an electrical connectioncapable of being pushed into an electrical junction.

The principal object of the present invention is, in the first place, tomake available an arrangement of the kind indicated above, which permitsa reflector fitted with a bulb or some other appropriate electricaldevice to be attached effectively and by simple means to an electricalcable in a separable fashion.

Said object is achieved by means of an arrangement in accordance withthe present invention, which is characterized essentially in that acoupling capable of being joined to an electrical cable, which couplingis in the form of a component attached to one end of the electricalcable in question by means of, for example, a screw or some otherfastening device and provided with an electrical junction with theability to conduct electricity, is so arranged as to function as a stopboth for an electrical device and for a holder capable of being joinedto the electrical device, in opposite directions.

The invention is described below as a preferred illustrative embodiment,in conjunction with which reference is made to the drawing, which showsa bulb and reflector connected together in a partially sectioned view.

At one end 1A of an electrical cable 1, which exhibits a number ofconductors 1¹, 1² and which is preferably strengthened by areinforcement 2 and is enclosed by a sheath 3, similar to a flexibleconductor, for example, a fastening arrangement 4 for an electricaldevice 5 of an appropriate kind is capable of being connected to saidelectrical cable 1. In the preferred embodiment the electrical device 5comprises a reflector 6 with an integral bulb 7, preferably a so-calledhalogen bulb. Said electrical device 5 exhibits a number of pins 8 or anelectrical connection of similar form, which is capable of being pushedinto contact with an appropriate electrical junction 9, for instanceholes.

A coupling 10, which exhibits the ability to conduct electricity and iscapable of being joined to an electrical cable 1 of the kind inquestion, for example by means of a screw 11 or some other appropriatefastening device which holds the electrical conductors 1¹, 1² securelyin position on said part 10, exhibits said matching electrical junctions9, so that the pins 8 of the bulb or other electrical connections can bejoined to said electrical conductors 1¹ 1² for the purpose of joiningthem to one another so that the bulb 7, etc., can be connectedelectrically so as to make contact in order, for example, to be capableof being lit at the desired moment. A casing 12, preferably in the formof a plastic hose, which is so arranged as to be shrunk by means of heatonto the electrical cable 1 and the coupling 10 so that it covers atleast a part of them, may be so arranged as to protect them from contactand against being contaminated with dirt, and from damp, etc.

A holder 13 of an appropriate kind, which is capable of being joined tothe electrical device 5, is so arranged as to be pushed against thecoupling 10 at the same time as the electrical device 5 is pushed by theholder 13 in the direction of the coupling 10, in conjunction with whichsaid coupling 10 is so arranged as to function as a stop both for theholder 13 and for the electrical device 5, although in oppositedirections 14 and 15, so that the electrical device 5, at the same timeas it is effectively restrained, is also capable of being pushedsecurely home so as to make good electrical contact. The holder 13 cancomprise one or more sprung tensioning elements 16, 17 attached to theelectrical cable 1, which are so arranged as to grip around theelectrical device 5, preferably at a conveniently thickened peripheraledge 5A of same. Said tensioning elements 16, 17, which may consist ofwire-like loops originating from a common and preferably divisiblesleeve 18 or some other sleeve-shaped attachment which is able to griparound the electrical cable 1, exhibit a holder part 16A, 17A which ispreferably wire-shaped and line-shaped, so that it can be snapped overand securely tightened against a segment-shaped part 58 of thepreferably circle-shaped reflector 6 or some other appropriateelectrical device 5.

The two loops 16, 17, the length of which is so adapted that they areable to be snapped over the peripheral edge 5A of the reflector, etc. 6,when the sleeve-shaped attachment 18 is displaced towards its front endposition and is pushed against the coupling 10, as shown in the drawing,endeavour to force the reflector 6 with its associated bulb 7 and theelectrical connections 8 in the direction of said coupling 10, so thatthe capacity of making good electrical contact is achieved at the sametime as the electrical components are held together.

An attachment element of a previously disclosed kind may be arranged onthe cable 1 at its end 1A facing away from the attachment for theelectrical device 5 in order to permit the cable 1 supporting the bulb 7and the reflector 6, etc., to be attached at an appropriate position, sothat the cable 1 can be bent to a suitable shape to enable it to bedirected towards a desired point of illumination, for instance.

The invention is not restricted to the illustrative embodiment describedabove and shown in the drawing, but may be modified within the scope ofthe Patent Claims without departing from the idea of the invention.
